This invention relates to an improved fabric structure and its primaryobject is to provide a ground or base fabric area having spaced tightlywoven areas extending weftwise of the fabric. Between the spaced area oftightly woven ground fabric there are provided loosely woven or floatedareas wherein a substantial number of warp yarns and weft yarns arefloated across these loosely woven areas, the floated areas also beingspaced longitudinally or warpwise of the fabric with the weftwisetightly woven areas also being spaced longitudinally or warpwise of thefabric between the floated areas.

Upon a predetermined number of p cks of the ground fabric being woven toform said tightly woven and loosely woven areas extending weftwise ofthe fabric, a relatively small number of picks of an effect or designfilling, preferably of a greater number of plies or strands per pickthan the filling used in forming the ground fabric, are then looselywoven. Now, as these effect fillings are beat-up at the fell of thecloth, due to the previous tightly woven areas and the loosely wovenareas, the effect filling will not extend in a straight line between theselvages of the fabric but will extend in an irregular or sinuous pathacross the fabric.

Thus, upon a series of repeats of the tightly woven and loosely wovenareas of the ground fabric being woven and upon the loosely woven effectfilling yarns being woven between each of the rep-eats of the tightlyand loosely woven ground yarns, a product is formed having a pluralityof sinuous yarns extending thereacross defining the tightly woven areassince, upon the sinuous effect filling yarns being thrown across thefabric, they are bunched or crowded together at the points at which theground yarns were loosely Woven, and a preceding number of picks of theeffect yarns are spaced apart from the subsequent filling effect yarnsat opposed edges of the tightly woven areas of the ground yarns, thesubsequent design or effect yarns being crowded against the precedingeffect or design yarns between the tightly woven areas of the groundyarn, due to the floated portions of the ground yarns, at spaced pointsthroughout the width of the woven material.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which Figure 1 is a schematic view showinga portion of the means employed for weaving the fabric; Figure 2 is afragmentary view of a piece of a typical fabric woven to embody thefeatures of 9 Claims.

Figure 8 is a chart of the pattern employed on a pattern means, such asa pattern chain of a loom, for control of the heddles or harnesses.

In Figure 1, there is shown a typical arrangement of the variouspertinent Weaving instrumentalities of a loom which may be employed inweaving the particular fabric shown in Figures 3 to 8, inclusive. Thisparticular loom may be of a type such as is manufactured by Crompton 8:Knowles of Worcester, Massachusetts, and which is known as a model C-4loom with a pattern controlling mechanism such as a dobby head. It willbe evident from the context that many other types of looms may be usedand also the number of heddles or heddle frames employed may vary inaccordance with a desired pattern. Also, many other pattern mechanismsmay be used in association with the loom such as a jacquard mecha-.nism. Since at least two different types of weft or filling yarns areemployed, it is evident that a suitable shuttle changing mechanism foraccommodating at least two shuttles should also be employed inassociation with the loom on which this fabric is Woven.

Referring to Figure 1,a sheet of warp yarns, designated generally at W,is directed from a warp beam 30 over a whip roll 3| and extendsforwardly over and under a pair of spaced rods 32 and 33 after which thevarious yarns of the sheet of warp W are passed through a plurality ofsuccessively arranged vertically movable heddle frames or heddles HI toH8, inclusive, and HI to H8, inclusive, the exponent of each of theselastnamed reference numerals corresponding to the exponent of thereference numerals applied to the Warp yarns in Figure '7 and indicatingthe warp yarn or strand which is controlled by the heddle. Although, 16heddles or heddle frames are shown in Figure 1, it is to be understoodthat any desired number of heddles or heddle frames may be employed inaccordance with a desired pattern and depending upon the type of patternmechanism employed in effecting operation of the heddles or heddleframes.

After the warp yarns have passed through the corresponding heddles orheddle frames, they then pass through a conventional reed 35 carried byan oscillatable lay 36 across which filling yarns, to be presentlydescribed, are projected in the usual manner to lay the filling yarns inthe shed formed by the warp yarns W and to beat the warp yarns into thefell of the cloth or at the beat-up point of the lay indicated at B inFigure 1 to thus form fabric or cloth C.

Now, referring to Figure 7, there is shown the essence of thearrangement of a few of the warp yarns and weft yarns to produce afabric substantially as shown in Figures 2 to 6, inclusive, and this maybe readily compared with the chart of the pattern shown in Figure 8employed on the usual pattern means for the loom. It is to be assumedthat the fabric is formed from the top to the bottom of the illustrationin Figure '7, the weft or filling yarns extending crosswise of Figure '7and the warp yarns extending lengthwise or from the top to the bottom ofFigure '7.

There is a single repeat in the patterning with respect to the weft orfilling yarns shown in Figure 7, there being a group of twenty-sixsuccessively woven base or ground filling yarns Fl to F26 in a group,identified as group IA in Figure '7, following which a group of foureffect or design filling yarns Ell to E4 are woven successively. Thentwenty-six additional ground filling yarns Fl to F26, inclusive, arewoven successively in a group identified as group 2A in Figure '7. Agroup of four additional effect filling yarns identified at El to E4,inclusive, are then woven to complete a single repeat in the number ofpicks which are employed in knitting the particular fabric shown inFigures 2 to 4, inclusive.

It will be observed in Figure '7 that the warp yarns are also dividedinto repeats, each of which includes at least one first group of eightwarp yarns, identified as group I, and at least one second group ofeight warp yarns, identified as group 2. The areas identified by thevarious groups are enclosed by broken lines so their scope may beclearly discernible as the description proceeds. The first groupincludes warp yarns indicated at WI to W8, inclusive, and the secondgroup includes warp yarns indicated at WI to W8, inclusive. Each repeatof the warp yarns should include a plurality of side by side firstgroups and a plurality of side by side second groups, the number offirst groups being substantially the same as the number of second groupsin each repeat of the Warp yarns. In other words, referring to Figures 2and 3, there are shown a plurality of Warpwise and Weftwise spacedtightly woven areas, indicated at 40, between which are woven sleazy orloosely woven areas 4l, these loosely woven areas 4| being visible atthe back of the fabric only, as shown in Figure 3, since they arecovered by the effect or design filling yarns in Figure 2.

It will be observed in Figure 7 that the warp yarns W3 and WT in group Iare interwoven loosely with some of the weft yarns Fl to F26 at one sideof the loosely woven effect filling yarns El to E4, inclusive, and theother warp yarns WI, W2, W4, W5, W6 and W8 are floated on the top of thefilling yarns Fl to F26, inclusive, in group IA, while at the other sideof the effect filling yarns El to E4, inclusive, the warp yarns WI toW3, inclusive, are tightly interwoven with the ground filling yarns ingroup 2A, including the filling yarns Fl to F26, inclusive.

On the other hand, the warp yarns W l to W8 are tightly interwoven withthe ground filling yarns Fl to F26 in group IA while they are looselyinterwoven with the ground filling yarns Fl to F26 in group 2A as abovedescribed for the warp yarns in group I. Thus, the areas indicated at 40in Figures 2 and 3 are woven in the manner in which the warp yarns WI toW8, inclusive, and the ground filling yarns Fl to F26, inclusive, ingroup 2A are interwoven (Figure '7) and in the manner in which the warpyarns WI to W8, inclusive, are interwoven with the weft yarns Fl to F26in group IA. It is evident that each of the areas 40 will include asubstantial number of groups of warp yarns, such as the groups I and 2in Figure 7, in order to complete a repeat such as the repeat R inFigure 2. It will be noted that this repeat R embraces twolongitudinally extending rows of off-set or staggered areas 46.

Referring now to the upper right-hand portion of Figure 7, it will beobserved that the warp yarns and weft yarns embraced by the respectivegroups 2 and IA are interwoven to form a very dense and firm fabric. Themajority of the ground warp yarns in the area embraced by groups I andIA float, without interweaving, on the face of the fabric and these warpyarns, including the warp yarns WI, W2, W4, W5. W6 and W8 are notinterwoven at all with the weft yarns in group IA. These last-named warpyarns shall be termed as face warp yarns for purposes of description.

Inasmuch as the face warp yarns float on the face of the fabric, it isobvious that the portions of the filling yarns therebetween will floatat right angles on the back of the fabric. These long floats of thefilling yarns on the back of the fabric would be objectionable and,therefore, the two warp yarns W2 and W7, which shall be termed as backwarp yarns, are alternately interwoven, for example, with every fifthpick of the floated filling, that is, each of the warp yarns W2 and W!are interwoven, for example, with every tenth ground filling yarn. Theportions of the warp yarns which serve as back warp yarns are shaded bystippling for purposes of clarity. The length of floats may be variedwithout departing from the spirit of the invention.

As heretofore stated, a plurality of groups of warp yarns, such as thewarp yarns in group I, are repeated in side by side relation inaccordance with the size of the areas 40 which extend transversely ofthe fabric (Figure 2) and these groups of warp yarns, which areinterwoven with the filling yarns in the manner in which the group I ofwarp yarns is interwoven with the group IA of the weft yarns in Figure'7, would form a very open and sleazy weave on the back of the fabric,as shown in Figure 3, which will partly cover and thus conceal the longfloats of the filling in this area without interfering with thedistortion of the effect filling.

After a predetermined number of the ground filling yarns have been castacross the fabric,

such as the twenty-six filling yarns Fl to F26, inclusive, in Figure 7,the lesser number of picks, for example, four picks of relatively heavyeffect filling are then interwoven with the warp yarns. It will be notedthat the area including the warp yarns in group 2 and the filling yarnsin group 2A is formed in substantially the same manner as the area inwhich the warp yarns in group I are interwoven with the weft or fillingyarns in group IA. Conversely, the warp yarns in group I are interwovenwith the filling yarns in group 2A in the identical manner in which thewarp yarns in group 2 are interwoven with the weft or filling yarns ingroup IA.

Now, assuming there are several repeats of the warp yarns in group 2disposed on the right of group 2, it will be noted that the warp yarnsW4 is floated above all of the ground filling yarns in group 2A as wellas the effect filling yarns E l'and El while the warp yarns W2 and W5are floated above all of the ground filling yarns in group 2A, butextend beneath the adjacent effect filling yarns E4 and El and then passabove the effect filling yarns E3 and E3 at opposed ends of the areadefined by the ground filling yarns in group 2A.

On the other hand, the warp yarns WI and W6 are floated above all of theground filling yarns in group 2A and pass beneath both of the eifectfilling yarns E4 and E3 and above the effect filling yarn E2 at one endof the group 2A of filling yarns while, at the other end of group 2A ofthe ground filling yarns, the warp yarns WI and W6 pass beneath both ofthe effect filling yarns El and E2 and then pass above the effectfilling yarn E3.

The warp yarn E8, of course, passes beneath the three effect fillingyarns E4, E3 and E2 after passing above the effect filling yarn El andis then floated above all of the ground filling yarns in group 2A afterwhich it passes beneath the three effect filling yarns El, E2 and E3 andthen passes above the effect filling yarn E4 to subsequently beinterwoven with the filling yarns to form a tightly woven area adjacentthe lower surface of the effect filling yarn E4 in Figure '7 which isidentical to the tightly woven area adjacent the upper surface of theeffect filling yarn El in Figure '7. The fioats of the warp and fillingyarns need not be as described, as they might be interwoven at shorteror longer intervals if desired. 1

It is well known to those familiar with the art that, upon each beat-upstroke of a reed, such as the reed 35 in Figure l, the reed 35 advancesslightly beyond the point at which it engages the fell of the cloth and,although the reed 35 may be perfectly straight throughout its length,the floated portions of the ground filling yarns, which extend beneaththe fioated portions of the warp yarns, such as are defined by thegroups 2 and 2A, are beat-up over one another, since the warp yarns areunable to hold them in the same plane as the upper or lower surfaces ofthe adjacent tightly woven areas such as the area defined by groups land 2A in Figure '7.

Therefore, upon weaving the area defined by groups l and IA, the effectfilling yarns El, E2, E3 and E4 would be beat-up thereagainst and wouldtend to roll over the upper surface of the loosely woven ground fabric,defined by groups I and lA in Figure 7, and these effect filling yarnsEl to E4, inclusive, would be beat-up against the previous beat-upground filling yarn F26 in the area defined by groups 2 and IA. Thus,the normal path of the effect filling yarns El to E4, inclusive, wouldbe interrupted, these fillings being distorted or caused to turn upwardat the lefthand portions thereof in Figure '7 and the right handportions of these effect fillings El to E4, inclusive, would be causedto extend substantially in a straight line.

Thus, upon the tightly woven area defined by the warp yarns in group Iand the filling yarns in group 2A being woven and the loosely wovenarea, including the warp yarns in group 2 and the filling yarns in group2A, being woven, the tightly woven area, including the warp yarns ingroup I and the filling yarns in group 2A will be disposed in off-setrelation to the tightly woven area, including the warp yarns in group 2and the weft or filling yarns in group IA, with the upper edge of thetightly woven area having the filling yarns in group 2A being disposedsubstan tially midway of the tightly woven area, having the warp yarnsin group 2 and the weft yarns in group IA therein,

iNow, due to the fact that the fioated portion of the warp yarn, such asthe warp yarn W4 in group 2, extends above all of the ground fillingyarns in group 2A as well as the bordering effect filling yarns E4 andEl and the warp yarns on each side of the warp yarn W4 passes beneaththe effect filling yarns E4 and El but over the effect filling yarns E3and E2, it is evident that upon the right-hand portions of the efiectfilling yarns El, E2, E3 and E4 being beat-up against the effect fillingyarns E4, the two adjacent effect filling yarns E4 and Elwill be beat-upagainst each other and the yarns E3 and E2 adjacent the remote surfacesof the yarns E4 and El will tend to move beneath the yarns E4 and Elthere between in the course of other beat-up strokes of the lay 36. Thesame is substantially true of the remaining effect filling yarns E2, El,E3 and E4 resulting in the effect or design filling yarns extending in asinuous path and forming an embossed sinuous design on the ground fabricarea substantially as shown in Figures 2 and 3, this also being clearlyillustrated in Figures 5 and 6.

Now, due to this particular arrangement of the effect filling yarnsadjacent the areas having floated yarns therein, upon the fabric beingpassed through various finishing operations, such as vigorous tumblingand washing operations, the floated warp yarns, which extend across theloosely woven areas between adjacent spaced tightly woven areas, tend toshrinka greater amount than do the tightly woven areas since it isevident that a loose or single yarn will shrink a greater amount thanwill a plurality of tightly interwoven yarns.

This causes the tightly woven areas to be pulled slightly towards eachother and, in so doing, the distorted or sinuous effect filling yarnsare caused to roll under each other, this being partly due to the factthat the warp yarns which are floated over the ground filling yarns alsoextend above the two adjacent effect filling yarns while the nextadjacent floated or face warp yarns on each side of this first-namedwarp yarn extend beneath the immediately adjacent effect filling yarns,such as the effect filling yarns El and E4 in Figure 7, and pass abovethe next adjacent effect filling yarn but pass beneath the remainingeffect filling yarns, this being repeated for as many effect fillingyarns as there may be disposed between the-tightly woven warpwiseextending areas.

It is thus seen that the floated portions of the warp yarns tend to leadthe effect yarns which are immediately adjacent the spaced tightly wovenareas 40 beneath the yarns which are disposed at the juncture ofadjacent sinuous areas, this being clearly shown in Figure 4. It is alsoseen that a substantial distortion of the effect filling is caused bythe dense and firmly woven portions of the fabric exerting a pressureagainst the effect filling yarns as the fabric is woven and, since thereis no interfering back pressure on the effect fillings from the oppositeopen sleazy portions 4| of the fabric, the effect filling yarns will beforced over the portions 41 meeting the immediately adjacent roup ofeffect filling yarns which are forced into the adjacent sleazy portions4| of the fab ric from the opposite side thereof.

Now, .although there are shown twenty-six ground filling yarns betweeneach of the groups of effect filling yarns and four effect filling yarnsbetween the groups of ground filling yarns, it is evident that thenumber of effect filling yarns as well as the ground filling yarns maybe decreased or increased in accordance with a desired pattern. However,it has been found that the most favorable results are obtained byproviding repeats of the ground Weft or filling yarns including fiveyarns in each repeat with the fifth weft yarn being interwoven with thethird warp yarn in each instance in weaving the floated areas in themanner in which the warp yarns W3, in Figure 7, is interwoven with theweft yarn F6. The particular effect filling yarns shown in the drawingsappear to be about three times the diameter of the ground warp andfilling yarns and it is preferable that these effect filling yarns beplied with relatively low twist in the plied yarns to form a scallopedoutline to the effect yarns in the cloth. For other effects, hardtwisted or fancy efiect filling yarns may be employed.

It is to be understood that the yarn from which the effect filling isformed may be identical to the yarn from which the ground fabric area isformed, the types of yarn employed in weaving the ground fabric area andthe design areas formed of the effect filling yarns varying inaccordance with a desired pattern effect to be produced. A fabric wovenin accordance with the present invention may be employed in themanufacture of bedspreads, draperies, upholstery and the like.

Although, a relatively plain weave is shown in the drawings asrepresentative of the tightly woven areas 40, this plain weave may besubstituted with a fancy weave wherein various designs may also beincorporated, although, in this instance, the amount of distortion ofthe effect filling yarns as they are beat-up by the reed 35 may berelatively substantially reduced, the greatest amount of distortion inthe effect filling yarns being obtained with a plain weave.

The manner in which the selvage is formed in a fabric woven inaccordance with the features of this invention is shown in theright-hand portions of Figures 2 and 3. It is evident that upon foureffect filling yarns being thrown across the lay 36, the effect fillingyarns may be severed as the tightly woven areas of the ground fabric arewoven so that the starting point of the next group of four effectfilling yarns will not be encumbered by the portions of the yarn whichmay extend across the tightly woven areas at the selvages of the fabric.

However, considerable time would be consumed in performing thisoperation or special equipment may be required for this purpose.Therefore, it is preferable that the effect filling yarns extend alongthe selvage of the fabric adjacent the selvages of the tightly wovenareas without being woven into the fabric as at 42 and, in order toprevent the selvage from being pulled inwardly at the loosely wovenareas as a result of the effect fillin yarns extending along the selvageof the tightly woven areas and entering the loosely woven areas, it ispreferred that both the effect filling yarns and the ground fillingyarns be held in alinement with the mean selvage of the fabric, as wovenin the tightly woven areas, as it is woven in the loosely woven areas atthe selvage of the fabric.

A typical apparatus which may be employed for this purpose is clearlyshown in Figure 11 of my co-pending application, filed September 22,1950, Serial No. 186,182 and entitled Pattern Controlled VariableBeat-Up and Pile Warp Feed Mechanisms. It is to be understood, however,that the manner of providing tension in the weft yarns at the time ofweaving the loosely woven areas adjacent the selvage of the fabric neednot necessarily be limited to the apparatus shown in said co-pendingapplication.

In the drawings and specification, there has been set forth a preferredembodiment of the invention and although specific terms are employed,they are used in a generic and descriptive sense only and not forpurposes of limitation, the scope of the invention being defined in theclaims.
